Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a hydraulic valve control system for a marine vessel such as a valve remote control system in a ballast line, a bilge line, a fuel line or a fire extinguishing line of a marine vessel. About.

[Conventional technology]

Conventionally known marine valve remote control systems are shown in FIGS. 6 and 7. FIG.

Valves consisting of ball valves, king valves or butterfly valves
A large number of valve units VU each having a hydraulic actuator 82 composed of a hydraulic oscillating motor for driving the valve 81 are arranged at various places in the ship. For example, such valve units VU are usually arranged at 50 to 300 places on the ship.

Therefore, a hydraulic pump unit 84 and a solenoid valve stand 83 serve as power sources for a large number of scattered valve units VU.
A control console 85 is provided at a location and centrally controls the control console.

[Problems to be solved by the invention]

According to the remote control system for a marine valve described above as a conventional example, it is necessary to provide not only an electric line 86 but also a hydraulic line 87 as shown in FIG. That is, a hydraulic pipe must be provided between the hydraulic actuator 82 of the valve unit VU and the electromagnetic valve stand 83 arranged at various places in the ship. However, as described above, the location of the valve unit VU is usually 50 to 300, so the number of hydraulic pipes is extremely large, it takes a considerable period of time for piping work, and enormous costs must be borne. There is a problem that it does not.

Further, conventionally, since the hydraulic pump unit 84 disposed in one place drives 50 to 300 valve units VU, the hydraulic pump unit 84 is a large-sized device having a large output, and as a result, , Space on board,
There are problems to be solved in terms of noise and vibration, energy saving, and the like.

[Means for solving the problem]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and provides a remote-controlled marine hydraulic valve control system that does not require hydraulic piping in a marine vessel, and that has low noise and energy saving.

In view of this, the present invention is configured as means by arranging a large number of valve units VU each including a valve 1 and a hydraulic actuator 2 for driving the valve at various places on the ship.
In a system for remotely controlling the actuator 2 of the valve unit VU: each valve unit VU
The hydraulic system HS is constituted by an individual package unit PU in which a hydraulic system HS is assembled, and the hydraulic system HS is connected to the actuator 2 and constitutes a pressurized tank having a pressurized cylinder 9. A unit including a hydraulic drive source 5 for flowing hydraulic oil charged from the pressurized oil tank 7 to the actuator 2, and a switching means 3 for switching the pressure oil flow to the actuator 2 forward and reverse. The individual package unit PU is constituted by assembling the unit HS of the hydraulic system and the valve unit VU.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1 and FIG. 2, a large number of valve units VU each including a valve 1 and a hydraulic actuator 2 including a hydraulic rocking motor for driving the valve are mounted on various parts of the ship, for example, on a ship. As in the case of the above-described conventional example, a system is provided at ~ 300 locations to remotely control each valve unit VU.

Therefore, each valve unit VU is provided with an oil tank 7 connected to the actuator 2 and a hydraulic drive source 5 for flowing pressure oil from the oil tank 7 to the actuator 2.
And a hydraulic system HS including switching means 3 for allowing the pressure oil flow to the actuator 2 to be switched between forward and reverse. The valve unit VU and the hydraulic system HS are assembled for each valve unit VU. Package unit PU.

In the preferred embodiment shown in FIG. 1, the oil tank 7 constitutes a pressurized tank provided with a pressurized cylinder 9 and constantly pressurizes hydraulic oil in the tank to about 0.5 kg / cm ² . This allows flexibility in the mounting position and directionality of the package unit PU. For this reason, the package unit PU can be freely arranged in a vertical position such as an upright direction or an inverted direction, or a horizontal position such as a horizontal direction or an inclined direction, and the supply of pressure oil to the actuator 2 is guaranteed.

In the configuration shown in the figure, the hydraulic drive source 5 constitutes a hydraulic pump 5b driven by an electric motor 5a, and the switching means 3 comprises a poppet type solenoid valve 3a for switching the oil path between forward and reverse and a relief valve 3a. Although it is configured by a hydraulic circuit including the valve 3b, the present invention is not limited to such a configuration. For example, a configuration in which the actuator 2 is reciprocated by driving the hydraulic pump 5b itself forming the hydraulic drive source 5 in the normal and reverse directions. Is also good.

The package unit PU, as shown in FIG.
Two-story arrangement, electric motor 5a, hydraulic pump 5b,
The relief valve 3b, the oil tank 7 and the actuator 2 may be arranged, and the poppet type solenoid valve 3a and accessories may be installed on the second floor.
m, 26 cm wide, 29 cm high, weighs about 5 kg, making it possible to construct an extremely compact structure.

According to the configuration of the above-described embodiment, the package units PU as described above are arranged at various places on the ship. Therefore, when constructing a remote control system for each package unit PU, as shown in FIG. It is sufficient that the central control mechanism including the / A converter 11 is connected to each package unit PU by an electric line, and the conventional hydraulic piping on board is not required.

Then, when remotely controlling the package unit PU via the electric line, one valve unit VU is driven by one corresponding hydraulic system HS, so that the power source is small and sufficient. As a result, the space inside the ship can be saved, which contributes to the reduction of noise and vibration, and is also advantageous in terms of energy saving.

The following table shows a comparison between the above-described conventional example and the embodiment of the present invention.

[Effects of the Invention] According to the present invention, in a remote control type hydraulic valve control system for a marine vessel, an individual package unit PU in which a hydraulic system HS is assembled for each valve unit VU is configured. There is a remarkable effect that it is possible to eliminate the need for in-ship piping which required cost and a long construction period, and at the same time, there is a special effect that it contributes to space saving, low noise and vibration, and energy saving.

In particular, according to the present invention, a separate package unit PU is formed by connecting the hydraulic system unit HS and the valve unit VU, and such a package unit
Since the PU can be installed at required places in the ship, it can be easily installed even in a narrow space where conventional piping is difficult, and the purpose of the hydraulic valve control system can be completed.

When mounting the package unit PU in such a small space, it is necessary to mount the package unit PU in a limited posture and direction, such as a vertical posture such as an upright direction or an inverted direction, or a horizontal posture such as a horizontal direction or an inclined direction. According to the present invention, the oil tank 7 of the hydraulic system HS in the unit PU is
, And the hydraulic oil in the tank 7 is charged to the actuator 2 at a predetermined pressure, so that the valve unit VU is always good regardless of the attitude and direction of the package unit PU. It is possible to make the mounting posture and the directionality of each package unit PU assured.
By constructing the pressurized tank 7 having the pressurized cylinder 9, it is not necessary to separately provide a pump or the like, and the advantage of the mounting space due to the compactness of the unit is exhibited. It has an excellent effect in that it has achieved its purpose.
